CatTools Free?

I am running a free trial of CatTools. This has expired.

As this is a home lab setup and I’m only looking to back up a single Cisco ASA, I figured this would automatically downgrade to the "Free" version (which allows a single device)?

This hasn't happened. The product is now in an "Unlicensed" state, and everything is now understandably blocked.

Is the Free version still an option for a single device?
If so, how can I "re-licence" it for the Free version.
